The driving shaft is to make, use, and practice thesame.

This invention relates to certain new and driven to the left by pulley25 suitably belted to a source of power.

useful improvements in vegetable peeling The peri hery of the drum 19 isprovided machines.

The invention has for its object the prowith suitab e mountings 26 forthe reception duction of a simple and inexpensive machine of the rods 27upon which the brushes 28 are fixed. These brushes are preferably set onof this character constructed to remove the outer skins of vegetables,with minimum a plane tangential to the periphery of the drum, wherebythe potatoes, or other obwaste, and Without injury to the edibleporjects, are caused to travel up the elevating tion thereof.

Broadly stated the invention comprises side of the drum. Were thebrushes not so an inclosed drum the inner circumference set the objectswould tend to accumulate at the bottom of the drum until forced round ofwhich is studded with a series of independent, sprmg actuated brushes;and a reby those ObJGCtS behind, thus placing an undue strain on thebrushes and interfering volving cylinder within the drum having I withthe uniform operation of the machine.

32 so that the plane of all of the brushes may be changed and locked ina fixed whereby only the outer skin, softened by a stream of waterpassing through the drum,

is loosened and removed by the abrasive position to suit the contours,or physical properties of the objects to be treated. The side 12 isremovable to permit access action of the brushes.

The invention will be hereinafter fully set forth and particularlypointed out in to or removal of the drum. the claims. The stems 15 ofthe brushes 16 are held In the accompanying drawings-Figure 1 Within thetubes 14 by the wire loops 33 (see is a side elevation of a machineconstructed Fig. 2) the bight of which engages the pin 34 with thisinvention, portions through the end of the stem; the open end of beingbroken away in cross section to disthe loop extends through, and thebent ends close the construction and arrangement of engage the edges ofthe holes in the washer underlying mechanisms.

When the operator deems charge trap 18 in any size from closed drumhaving brushes 5 objects to be treated, potatoes for instance,

are dumped into the drum through the open trap 17 which is then latched.The rotation of the drum carries them under the brushes 16 which recedesufficiently to permit them 10 to pass, and at the same time exertsufficient pressure to cause the abrasion necessary to remove the outerskin which has been loosened by the water admitted to the drum throughthe inlet pipe 40 and the spray head The irregular contour of'thevegetable causes it to rotate and travel about between the brushes insuch a manner that all of its surface is acted upon by the brushes whicheffectively remove the skin, the eyes and soft or defective spots.

If desired the machine may be made of sufficient diameter to permit acontinuous feed of potatoes. The machine is practical the large powerdriven machine to the smaller size operated by hand power for domesticuse.

I claim as my invention:-

1. A peeling machine comprising an inresiliently mounted about its innercircumference, and a revoluble cylinder within said drum having brushespivotally mounted on the periphery thereof adjacent the first mentionedbrushes, means for adjusting said brushes, inlet and outlet traps hingedto said drum, means for introducing a flow of water into said drum, andmeans for revolving said cylinder. 7

2. A peeling machine comprising an inclosed drum having brushes mountedabout its inner circumference, a revoluble cylinder mounted Within saiddrum, brushes provided with pivot rods mounted on the periphery of saidcylinder, and means for adjusting said rods to vary the planes of saidlast mentioned brushes.

3. A peeling machine comprising an inclosed drum having brushes mountedabout its inner circumference, a revoluble cylinder mounted within saiddrum, brushes pivotally mounted on the periphery of said cylinder, andmeans whereby the planes of said pivoted brushes may be simultaneouslyand uniformly varied.

4. A peeling machine comprising an inclosed drum having brushes mountedabout its inner circumference, a revoluble cylinder mounted within saiddrum, brushes pivotally mounted on the periphery of said cylinder, meansfor adjusting the plane of one of said pivoted brushes, and linksconnecting all of said pivoted brushes, whereby they are allsimultaneously controlled by said adjusting means.

5. A peeling machine comprising an inclosed drum, spring pressed brushesmounted about the inner circumference of said drum, a revoluble cylindermounted in said drum, brushes pivotally mounted on the periphery of saidcylinder, and means for simultaneously and uniformly varying the planesof all of said pivoted brushes.

In testimony whereof, I have hereunto set my hand this 30th day ofSeptember, 1907.
